Description

Technical Field

[0001] This utility model relates to the field of packaging box production technology, specifically to a gluing device for packaging boxes. Background Technology

[0002] Paper packaging boxes are collectively referred to as cardboard boxes. A cardboard box is a three-dimensional shape, composed of a multifaceted form created by the movement, stacking, folding, and enclosing of several constituent surfaces. In three-dimensional composition, surfaces play a role in dividing space; cutting, rotating, and folding different parts of the surface results in different emotional expressions. The compositional relationship of the display surfaces of a cardboard box requires attention to the connection between the display surface, sides, top, and bottom, as well as the placement of packaging information elements. Packaging boxes require gluing during processing. However, in traditional gluing devices for packaging boxes, the glue in the supply tank is prone to problems such as increased viscosity and decreased flowability after low temperatures or prolonged standing, leading to uneven gluing, glue breakage, or pipe blockage, which can easily affect the bonding quality of the packaging box. Excessively high glue viscosity can also cause sedimentation within the gluing machine, affecting glue dispensing. Utility Model Content

A Z-axis lifting mechanism adjusts the distance between the applicator head and the material to ensure appropriate gluing pressure. A servo motor drives the motion mechanism to achieve high-precision positioning. This is also existing technology and will not be described in detail here. The glue applicator body 3 is electrically connected to an external power source and is controlled by an external program. An L-shaped fixing frame 4 is fixedly connected to the top of the base 1.

The front of the two slide bars 66 is fixedly connected to the connecting shaft 67. The surface of the output shaft of the motor 64 is fixedly connected to the rotating bar 68, and the connecting bar 69 is rotatably connected to the rotating bar 68. The front of the limiting stage 63 is rotatably connected to the adapter bar 610, and the bottom of the adapter bar 610 is fixedly connected to the connecting plate 611. The heating machine 612 is fixedly connected to the connecting plate 611. By setting the swing heating mechanism 6, the heating can swing back and forth, dynamically moving the heating source to evenly cover and heat the glue in the glue supply box 5, maintaining the fluidity of the glue, reducing the risk of clogging, ensuring consistent glue thickness, maintaining glue dispensing effect, and achieving better bonding effect.

[0025] A heating element 11 is fixedly connected to the connecting plate 611. The heating element 11 ensures that the adhesive maintains an appropriate temperature and fluidity during the adhesive supply process, thereby guaranteeing the quality and efficiency of adhesive application. Heat is generated by current passing through a resistance wire and transferred to the adhesive in the supply box. The heating element 11 has a simple structure, high heating efficiency, and convenient temperature control. It is electrically connected to an external power source and controlled by an external program. Four positioning holes 7 are provided on the top of the base 1.

[0026] The quick-release receiving mechanism 8 includes four positioning rods 81 slidably connected to the inner walls of the four positioning holes 7 and a fixing block 82 fixedly connected to the top of the base 1. A receiving groove 83 is fixedly connected between the top ends of the four positioning rods 81. A spring rod 84 is fixedly connected to the right side of the fixing block 82. A buckle rod 85 is fixedly connected to the right end of the spring rod 84. A pull handle 86 is fixedly connected to the surface of the buckle rod 85.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] The working principle of this utility model is as follows: First, grasp the handle 86 and pull it to the left to drive the latching rod 85 to move synchronously to the left against the elastic force of the spring rod 84. Then, align the four positioning rods 81 and insert them into the four positioning holes 7 to initially position the receiving groove 83 on the base 1. Then, release the handle 86, allowing the latching rod 85 to spring back to its original position by the elastic force of the spring rod 84, so that the latching rod 85 is inserted laterally into the receiving groove 83 to lock the receiving groove 83 on the base 1. Next, start the heating machine 11 to heat it. Then, start the motor 64 to drive the rotating bar 68 to rotate through the output shaft. When the rotating bar 68 rotates, it drives the connecting shaft 67 above through the connecting bar 69, so that the upper part of the connecting shaft 67 is connected to the connecting bar 68. The connecting shaft 67 drives the upper slide bar 66 to slide back and forth in the upper limiting hole 65. At the same time, the connecting shaft 67 drives the adapter bar 610 to rotate back and forth in a fan-shaped motion trajectory on the limiting platform 63. When the adapter bar 610 moves, it drives the lower slide bar 66 to slide back and forth in the lower limiting hole 65 through the lower connecting shaft 67. While the adapter bar 610 moves, it drives the heating machine 11 to swing back and forth to heat through the connecting plate 611, expanding its heating coverage area of ​​the glue supply box 5. Then, the packaging box is placed on the conveying device 2 and the glue applicator body 3 is started to apply glue. The glued packaging box is conveyed by the conveying device 2 to the receiving trough 83 for collection.
